1 Interacting with the API - the basics

  1. Perform a first GET request, that searches for event venues in Germany (countryCode = "DE"). Extract the content from the response object and inspect the resulting list. Describe what you can see.
# load libraries
library(httr)
library(tidyverse)
library(rlist)
library(kableExtra)
# function to display a data frame more appealingly
print_df <- function(df, n = 10, scrollbox = FALSE) {
  
  # styling
  df_formatted <- df %>% 
    head(n = n) %>% 
    kbl() %>%
    kable_styling(bootstrap_options = c("striped", "hover", "condensed")) 
  
  # scrollbox
  if (scrollbox) {
    df_formatted <- df_formatted %>%  
    scroll_box(width = "100%")
  }
  
  # show data frame
  df_formatted
}
# get API key
apikey <- readLines("ticketmaster_api_key.txt", warn = FALSE)
# url for venues
url <- "https://app.ticketmaster.com/discovery/v2/venues"
# define params for API call
params <- list(apikey = apikey, countryCode = "DE", locale = "*")

# get response from API and extract content
venues_DE_first_page <- GET(url = url, query = params) %>% content()

# show response

The response of the API call is a nested list. On the first level there are three items:

  • _embedded contains the actual data we have requested. The value is a list itself. In this list, again, there is a list with all returned venues (each of which is a list, again)
  • _links contains the url that was used for the API call (excluding the apikey and the domain). In addition, it contains the urls for the first, next and last page.
  • page contains information about the returned page from the data source
  1. Extract the name, the city, the postalCode and address, as well as the url and the longitude and latitude of the venues to a data frame. This data frame should have the following structure:

2 Interacting with the API - advanced

  1. Have a closer look at the list element named page. Did your GET request from exercise (7) return all event locations in Germany? Obviously not - there are of course much more venues in Germany than those contained in this list. Your GET request only yielded the first results page containing the first 20 out of several thousands of venues. Check the API documentation under the section Venue Search. How can you request the venues from the remaining results pages? Iterate over the results pages and perform GET requests for all venues in Germany. After each iteration, extract the seven variables name, city, postalCode, address, url, longitude, and latitude. Join the information in one large data frame. Print the first 10 rows and the shape of the resulting data frame. The resulting data frame should look something like this (note that the exact number of search results may have changed since this document has been last modified):

3 Visualizing the extracted data

  1. Below, you can find code that produces a map of Germany. Add points to the map indicating the locations of the event venues across Germany.
plot_venues <- function(
    venues_df, 
    country, 
    lon_lat_ranges = NULL, 
    verbose = TRUE) {
  #' Plot venues in a country
  #' 
  #' @description Plot venues in a specific country as points on a map.
  #' 
  #' @param venues_df tibble. A data frame with the venue data
  #' (longitude and latitude have to be  numeric)
  #' 
  #' @param country character. The name of the country, needed for retrieving the 
  #' base map
  #' @param lon_lat_ranges list. A list that contains the ranges for longitude and 
  #' latitude to clip the data, only used if not NULL 
  #' (default = NULL)
  #' @param verbose logical. Whether it should be printed how many venues are
  #' not plotted for different reasons
  #' (default = TRUE)

    # print number of missing values

  1. You will find that some coordinates lie way beyond the German borders and can be assumed to be faulty. Set coordinate values to NA where the value of longitude is outside the range (5.866, 15.042) or where the value of latitude is outside the range (47.270, 55.059) (these coordinate ranges have been derived from the extreme points of Germany as listed on Wikipedia (see here). For extreme points of other countries, see here).
# call plotting function and pass extreme points
plot_venues(
  venues_df = venues_DE, 
  country = "Germany",
  lon_lat_ranges = list(
    longitude = c(5.866, 15.042),
    latitude = c(47.270, 55.059)
  )
)

4 Event locations in other countries

  1. Repeat exercises (9)–(11) for another European country of your choice. (Hint: Clean code pays off! If you have coded the exercises efficiently, only very few adaptions need to be made.)
# call function for Germany (country_code='DE')
